This invention-relates to improvementsin heaters, and more particularly to a charcoal heater for'freight cars and the like 1 1 i It is one of theobjects of the present invention to provide a heater which, exceptfor several small castings, is formedentirely of A further object of the invention to pro vide a heater of the class described i'n which the fire pot side'is retained in place bylthe grate which is secured by bolts the fire pot side being thereby readily removable for re pairs or replacement. l

' A further object of the invention is to provide a heater ofthe'class describedin which sparks from the fuel cannot escape from the heater. A further object of the invention is to provide a heater having means for regulating the feed from the hopper to the fire'pot.

A further object of the invention is to provide a freight car heater equipped with'a lighter adapted to hold inflammable substances for the purpose of igniting charcoal in the fire pot.

A further object of theinvention is to provide a heater in which the cover for the fuel reservoir or hopper is air tight when in closed A further object of the invention is to provide a heater of the class described which is of very simple construction, is strong and durable, is inexpensive to manufacture; is ef ficient in operation, and is well'adapted for the invention consists of the improved heater, and its parts and combinations as set forth in the claim, and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views: i

Fig. 1 is a vertical sectional view of the improved heater;

Fig. 2 is a plan view thereof; and

Fig. 3 is a cross-sectional view taken on line 33 of Fig. 1.

Referring now more particularly to the drawings it will appear that the heater includes a cylindrically shaped shell orscasing at'its lower end portion by a bottom 9.

The top ofthe shell is partially closed by a top member'll'whose edge portions are rolled or crimped into engagement with the rolled edge of the shell, as "shown in Fig. 1. The top member is provided with a medialcircular opening 12 5of a substantial size. 2 The edgesof the *top member adjacent the opening are flanged downwardly as at 13. 'Said opening 12 is normally closed by a cover 14:having an air-tightengagementwith the top member- As "shown'fin Figs-1 and 2, theicover is of a vdished formation and is provided onits upper surface within the dished portion with a I when the cover is positioned inthe opening and-turned, engage the projecting ends of the bar 16 to removably lock thecoverinposition. Aflchaim 19 secured to the cover and -to the topfimember-prevents the top from being entirely removed 'fromthe heater and lost. V Positioned within the: shell, approximately halfway'between its extremities, is a jdownwardlyand inwardly inclined funnel-shaped member 20 "ofshee't metal-and forming a hopdiametrically extending rib'15 of channel Q per.The upper edge portion of the hopper is riveted to the shell,'wh ile the lower edge portionof the hopper is crimped into enga'gement with a -member 21 foldedto form a slide track fora shut-ofi plate22 which is horizontally sjlidably mounted between por ti-ons ofthe-member 21 and is adapted to reg-- ister with the" open lower end I l The outer end portion of the shut-off plate 22-h-as hinged thereto an operating handle 24 which normally hangs in a vertical posiportion 23.0f .thehopp'erto controlthe same.-

3 wardly or withdrawn to open or close theopening 23 by theplate 22, as the case may be. The shell is slotted, as at 26, to permit passage v of the handle.

A circular throat member. 27 is positioned immediately below the opening 23 of thehopper ands'aid throat member engages the throat member 27 is surrounded bya cone de flector 29 which engages at its upperportion flanged portion'28 of the member 21. The

the member 21 and at its lower portion it is crimped into engagement-.jwith-the throat member, as at'30. Angle pieces 31fare riveted to the cone defle'ctorsand bolted :to the shell and said angle pieces have-secured-thereto a circumferential spark deflecting collar 32.

.Also crimped at-its upper ;edge portion with the lower portion of the throat member is an aperture-d, outwardly and downwardly inclined fire pot topmember 33, ofcircular formati-o'n The lower portion of said fire pot top carries -brackets 34 which hold bolts 35 which carry inspa ced relation 'a-conical grate member 36, the grate being held thereon by, nuts 37. A circular, vertically-positioned andapertured fire :pot side 38 is disposed in a groove 39 in thegrate-andtheup per edgeportion of the fire 'pot wside'iis o'vlerla ped by the fire pot top 33-. i elow the fire pot and grate and resting on an inner bottom member 40. is an ash pan 41 to receive ashes falling through the grate. Access to the ash pan is afforded bymeansof an opening 42 in the lower portion of-the shell,-normally closed by means of afvertical'ly slidable doors-43 movable in a door-runner 44. The door is normally held in closed position by a pivoted catch 45 adapted to engage'alug46. V

When the door is raised to open position, a lighter 47, mounted on a pivotal, horizontal arm48 may be moved routwardlythroughthe door opening and when so moved .thelighter will also serve to hold the door in open position. The lighter is adapted to contain-readifall through the grate into the *ashpan. Sparks from the fuel are deflected andarrested bythe cone deflector 29 and the collar 32 and cannot escape from the shell. If the fire pot, side at anytime requiresw removal for replacement or repairs, it can be readily removed byremovingthe nuts .37 and'dropping the grate 36.

From the foregoing description it willbe I seen that the improved freight car heater is of very-simple and novel construction and is well adapted for the purposes described.

-What I claim as my invention is:

In a heater, a sectional and readily detach able and removable fire pot comprising a downwardly andv outwardlyinclined 'fire' pot top, brackets carried by the lower periphery.

of said fire pottop, a conical ;grate'member disposed. below said firepot-top, saidfgrate member having an annular: grooved flange, bolts extending from said brackets through said flange, and a circular, vertically positioned .fire pot side having its lower edge disposed within the groove of said fiange and supported; by the grate member and overlapping at itsupper edge portion the lower edge portion of said firepot-topi In testimony whereof,-l a

- eonrzi lyinflammablematerial for thepurp'ose of It should also'be observed thatthe casing or shell, at desired place, is formedwi-th a plu rality of spaced apertures 51 topermit the escape of heat. c j

Ii -use, fuel, preferably charcoal, is 'dis-' posed within the hopperjof the heater and the fuel'is automatically fed by gravity into the fire pot, the speed of -feeiiling being controlled by the adjustable 'shutoif plate 22. Fuel in the fire-pot is ignited lay-means heretofore explained 'an'dthe ashes of'the spent fuel ggl I xmy signature.
